Ok well thats good. I know you are new and was just offering a suggestion.
As far as pulling CBs - I dont know how I feel about that. Theres really no reason for it unless overspeeding is a consistent thing for your airplane. A simple call to ATC will almost always rectify that crossing restriction situation and they rarely get mad. But thats just my experience.
I also think its crappy that your Captain puts you in any situation like yhat. Whether its exceeding the limitatons of the aircraft so horns are screaming or dealing with Mr. Stern type pax.
